Features

■ Low output ripple ■ 10 amp output current ■ 92 % efficiency ■ Low 0.5 ˝ profile ■ Power good ■ Remote sense ■ Adjustable Vout ■ Short-circuit protection with auto-restart ■ Fast transient response ■ High-temperature operation ■ Remote enable ■ Output precharge capability General Information The SLN10A adds a new meaning to low cost DC-DC converters. This non-isolated SIP uses a 5 V input to provide 10 Amps of output current at voltages ranging from 0.8 V to 2.5 V. The SLN10A output is adjustable by the user to provide any voltage within its range. Its extra low 0.8 V output will power even the latest in ASICs, microprocessors, and DSPs. The SLN10A has an industry standard pin- out, is 2 inches long, and only 0.5 inches high. Its total footprint is a space saving 0.75 in 2. Features include Enable/Disable, output voltage trim, remote sense, short circuit protection with auto-restart, fast transient response, and high temperature operation. The SLN10A is one of the most cost-effective DC-DC converters available. Input Specifications 5 VDC Nom. 5.5 VDC Max.

Use low ESR capacitors for V IN and VOUT bypassing. 2. Part is enabled when ENABLE (10) is left floating or grounded. 3. Apply 2.4 to 5 VDC to ENABLE (10) to disable (shut down) the part. 4. Use the table above to determine an R TRIM resistor for the desired voltage. 5. To get an intermediate voltage between 0.800 V and 3.500 V, use the equation at right.
